Description

Technical Field

[0001] This utility model relates to the field of hydrophone surround sound, and in particular to an auxiliary fiber arrangement mechanism for hydrophones. Background Technology

[0002] Fiber optic hydrophones can be applied in offshore oil and gas exploration, underwater acoustic physics research, and marine fisheries. High-frequency fiber optic hydrophones can be used to measure ultrasonic fields in water for medical measurements. Hydrophones feature low noise, a wide dynamic range, and strong resistance to electromagnetic interference and signal crosstalk. They are suitable for long-distance transmission and arraying; fiber optic transmission has low loss, making it suitable for long-distance transmission; and the integration of signal sensing and transmission improves system reliability. Furthermore, the use of lasers as a light source enhances the reliability of the system. Therefore, the demand for hydrophone production is increasing, making improvements in production efficiency an urgent priority.

[0003] As a key component of hydrophones, the traditional winding process of hydrophone rings mainly relies on manual fiber arrangement, which greatly limits the production volume of hydrophones. Furthermore, manual fiber arrangement suffers from poor consistency and inadequate quality control. Utility Model Content

[0004] This invention provides an auxiliary fiber arrangement mechanism for hydrophones, which solves the problems of poor consistency and low efficiency in manual fiber arrangement during hydrophone surround sound manufacturing.

A second tensioning mechanism is provided on the side of the guide wheel assembly near the hydrophone ring skeleton. The optical fiber starts from the fiber feeding wheel, passes through the guide rollers, and then passes under the first tensioning mechanism, and then passes around the guide wheel assembly and the second tensioning mechanism to reach the hydrophone ring skeleton.

[0007] In the preferred embodiment, both the first tensioning mechanism and the second tensioning mechanism include a swing arm rod, which is hinged to the vertical base plate and an encoder is provided at the hinge point. One end of the swing arm rod is provided with a rotatable dance wheel.

[0010] In a preferred embodiment, the clamping mechanism includes a movable platform, one end of which is provided with a forward extension rod, and one end of the forward extension rod is provided with a top cone, which abuts against the end of the hydrophone ring frame.

Detailed Implementation

[0022] Example 1: like Figure 1-7 In a hydrophone auxiliary fiber feeding mechanism, there is a fiber feeding mechanism 1, which includes a rotatable fiber feeding wheel 101. A transverse movement mechanism 2 is provided on one side of the fiber feeding mechanism 1. The transverse movement mechanism 2 includes a movable transverse movement base plate 201. A fiber guiding mechanism 3 and a fiber feeding mechanism 6 are provided on the transverse movement base plate 201. A fiber taking mechanism 4 and a tightening mechanism 5 are provided on the side of the transverse movement mechanism 2 away from the fiber feeding mechanism 1. A rotatable hydrophone ring skeleton 7 is provided on the fiber taking mechanism 4. The tightening mechanism 5 tightens the tail end of the hydrophone ring skeleton 7.

[0023] The fiber feeding roller 101 is controlled to rotate by a servo motor.

[0024] A visual inspection device 10 can be installed on the transverse base plate 201 via a bracket. The visual inspection device 10 faces the hydrophone ring skeleton 7 to monitor the fiber discharge point in real time.

[0025] In a preferred embodiment, the fiber guiding mechanism 3 includes a vertical base plate 301 connected to a transverse base plate 201. The vertical base plate 301 is provided with a guide roller 302 and a guide wheel assembly 303. A first tensioning mechanism 8 is provided between the guide roller 302 and the guide wheel assembly 303. A second tensioning mechanism 9 is provided on the side of the guide wheel assembly 303 near the hydrophone ring frame 7. The optical fiber starts from the fiber feeding wheel 101, passes through the guide roller 302, and then passes under the first tensioning mechanism 8, and then passes around the guide wheel assembly 303 and the second tensioning mechanism 9 to reach the hydrophone ring frame 7.

[0026] Because the guide wheel assembly 303 includes multiple wheels, it will affect the fiber tension to some extent. Traditional fiber guiding systems only install one tension detection and adjustment mechanism, which tends to monitor the fiber tension on the take-up side and ignores the tension detection on the release side. If the guide wheel assembly 303 malfunctions, such as the wheels getting stuck, the tension detection mechanism will detect an increase in tension and, after feedback, the control system will command the release wheel 101 to speed up, but the improvement will be minimal and may lead to fiber wear or breakage.

[0027] With dual-sided monitoring, if a guide wheel malfunction occurs, the tension of the first tensioning mechanism 8 and the second tensioning mechanism 9 can be compared. If the difference exceeds a certain range, an error can be reported in time to avoid damage to the optical fiber or the mechanism.

[0028] In the preferred embodiment, both the first tensioning mechanism 8 and the second tensioning mechanism 9 include a swing arm 901, which is hinged to the vertical base plate 301 and an encoder 903 is provided at the hinge. One end of the swing arm 901 is provided with a rotatable dance wheel 902.

[0029] The optical fiber passes under the dancing wheel 902. Due to its own weight, the dancing wheel 902 tends to sag and tension the optical fiber. When the fiber feeding rate of the fiber feeding wheel 101 is slower than the fiber take-up rate of the hydrophone ring frame 7, the optical fiber is tightened, the tension increases, and the dancing wheel 902 is lifted. The encoder 903 detects the forward swing of the swing arm 901 and sends a feedback signal to the control system to control the speed of the fiber feeding wheel 101 to increase. When the fiber feeding rate of the fiber feeding wheel 101 is faster than the fiber take-up rate of the hydrophone ring frame 7, the optical fiber tension decreases, the dancing wheel 902 descends, the encoder 903 detects the reverse swing of the swing arm 901 and sends a feedback signal to the control system to control the speed of the fiber feeding wheel 101 to decrease. Therefore, the addition of the dancing wheel ensures that the optical fiber tension is always dynamically balanced.

[0030] The swing arm 901 can be designed with multiple mounting holes along a straight line. A counterweight 904 can be installed at the other end of the swing arm 901. The initial tension of the optical fiber can be adjusted by changing the hinge position and the swing radius of the dance wheel 902.

[0031] In a preferred embodiment, the guide rollers 302 include two parallel rotatable vertical rollers 304, with a gap between the two vertical rollers 304 for the passage of optical fibers.

[0032] During fiber feeding, the horizontal base plate 201 moves to one side relative to the fiber feeding roller 101. Therefore, a vertical roller 304 needs to be set in the direction of movement to prevent the optical fiber from falling off the guide roller of the guide roller group 303.

[0033] One or a group of transverse rollers 305 perpendicular to the axis of the vertical roller 304 can also be set to restrict displacement in another direction.

[0034] In a preferred embodiment, the fiber take-up mechanism 4 includes a base 401, a first drive motor 402 is provided inside the base 401, a bearing seat 404 is provided on the base 401, a rotatable cantilever rod 405 is provided inside the bearing seat 404, one end of the cantilever rod 405 is connected to the shaft end of the first drive motor 402 through a synchronous belt mechanism 403, and the other end of the bearing seat 404 is provided with a clamp 406, which clamps one end of the hydrophone ring skeleton 7.

[0035] In a preferred embodiment, the clamping mechanism 5 includes a movable platform 507, one end of which is provided with a forward extension rod 505, and the other end of the forward extension rod 505 is provided with a top cone 506, which abuts against the end of the hydrophone ring frame 7.

[0036] The lower end of the moving stage 507 is a linear module, including a second drive motor 501, a lead screw mechanism 502, and a guide rail slider mechanism 503. A lead screw nut 504 is installed at the lower end of the moving stage 507 and is sleeved with the lead screw mechanism 502. The second drive motor 501 drives the moving stage 507 to move left and right.

[0037] In a preferred embodiment, the fiber feeding mechanism 6 includes a mounting base 601. The mounting base 601 is provided with two vertically arranged lifting modules 602, a longitudinal moving module 603, and a transverse moving module 604. The transverse moving module 604 is provided with a movable seat 609. One end of the movable seat 609 is provided with a rotatable rotating shaft 605, and it is also provided with a fiber pressing and blocking foot 607. One end of the fiber pressing and blocking foot 607 is provided with a locking clip 606, which is connected to the rotating shaft 605.

[0038] A third drive motor 608 is installed on the movable seat 609 to drive the rotating shaft 605 to rotate for fiber pressing. The lifting module 602, the longitudinal movement module 603, and the transverse movement module 604 are linear movement modules consisting of a lead screw-guide rail-motor, enabling the movable seat 609 to move in three dimensions, adjusting the position of the fiber pressing stop foot 607 and adapting to changes in the fiber pressing position due to an increase in the number of fiber layers. The mounting base 601 is connected to the vertical base plate 301, and the transverse base plate 201 drives the fiber guiding mechanism 3 and the fiber discharging mechanism 6 to move for fiber discharging.

[0039] Example 2: An auxiliary fiber arrangement mechanism for a hydrophone winding machine includes a fiber take-up assembly, a clamping assembly, a fiber release assembly, a fiber arrangement assembly, a guiding assembly, and an optical fiber auxiliary fiber arrangement mechanism assembly.

[0040] The fiber take-up assembly is mainly used by the servo motor to drive the frame to take up fibers at a stable speed according to the set fiber take-up speed; The clamping assembly is a tooling that fixes the skeleton inside the bearing, thus clamping the skeleton. The fiber feeding assembly is driven by a servo motor that provides real-time rotation speed based on real-time feedback parameters, thereby maintaining stable tension on the optical fiber along the path. The fiber arrangement assembly is equipped with a high-precision lead screw guide module, which has high positioning accuracy. Its function is to act as a displacement slide for winding optical fibers on the skeleton. Each time an optical fiber is wound, the slide moves one optical fiber diameter distance, and the winding length is achieved by winding back and forth.

[0041] The guide assembly is an integrated component that monitors winding tension, length, and other parameters online.

[0042] The fiber optic auxiliary fiber arrangement mechanism is used to wind the optical fiber onto the hydrophone frame, which acts as a fiber stopper and compressor, ensuring that the optical fiber is wound onto the frame without gaps or overlaps.

[0043] The process has been transformed from manually winding optical fibers using tools and pens to automatically pressing and blocking the fibers with fiber clamping feet, ensuring that there are no gaps or fiber overlaps during the winding process. This increases efficiency by half and reduces the workload of operators.

[0044] First, the fiber distribution tray is manually placed on the fiber delivery assembly. Then, the optical fiber is wound onto the guide assembly and then onto the hydrophone ring frame for fixation. The fiber take-up assembly is then activated to begin winding. The fiber delivery clamping foot in the auxiliary fiber delivery assembly presses down onto the frame to block and press the last turn of fiber. The auxiliary fiber delivery assembly moves along with the fiber delivery assembly. For each rotation of the take-up assembly, the fiber delivery assembly moves a distance equal to one fiber diameter. The number of turns required for each layer is calculated by converting the frame length and the fiber diameter. The number of turns required for each layer and the total winding length are set on the touchscreen. After the parameters are set, winding begins, starting from left to right and then from right to left, repeating this process to achieve the required length.

[0045] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
